The High Court is to rule this afternoon on whether to stop members of Sean Quinn's family from alleged asset-stripping of their overseas business group.
Anglo Irish Bank, which is owed around €2.8bn, initiated the proceedings.
There have been strong exchanges between the two sides ahead of today's ruling with former Quinn group chairman Sean Quinn alleging that 38 years of his hard work to build the companies has been destroyed by Anglo Irish Bank in less than five months.
He also claimed Anglo was pursuing a vendetta against him, and putting jobs at risk.
Anglo alleges the Quinns have been asset-stripping their overseas property interests in countries including Ukraine, Russia, Sweden and Cyprus.
The High Court is to rule this afternoon whether to impose restrictions on the Quinns. It is also to decide whether it has the jurisdiction to hear the case in Ireland.
